The Myth of “Settled” Climate Science: A Revelatory Study on Cloud Formation

Trees, Clouds, and the Unsettling Truth about Climate Science

In a recent revelation from the international CLOUD project at the nuclear research center CERN, researchers have identified sesquiterpenes—gaseous hydrocarbons released by plants—as a pivotal factor in cloud formation. This study, published in the journal Science Advances, might just be the wrench in the works for those who have long touted the notion of “settled” climate science.

The Intergovernmental Panel on Climate Change (IPCC) has been confidently projecting that the global climate will warm by 1.5 to 4.4 degrees Celsius above pre-industrial levels by 2100. Yet, these projections are riddled with uncertainties. For instance, in a worst-case scenario, the temperature could swing anywhere between 3.3 to 5.7 degrees Celsius. Such a vast range hardly inspires confidence.

The root of these uncertainties? A glaring lack of understanding of the intricate processes occurring in our atmosphere. The CLOUD project, in its quest to demystify these processes, has been delving deep into the enigma of cloud formation.

Clouds, as it turns out, are not just fluffy white entities in the sky. Their formation and behavior have profound implications for the planet’s temperature. While it’s known that clouds reflect solar radiation, cooling the earth’s surface, the exact mechanics of their formation remain elusive.

Aerosols, both natural and man-made, provide the condensation nuclei essential for cloud formation. However, a significant portion of these nuclei form in the air when gaseous molecules combine, turning into solids—a process known as “nucleation” or “new particle formation” (NPF).

While the role of anthropogenic gases like sulfur dioxide is somewhat-documented, the study has shed light on the underestimated influence of natural gases like sesquiterpenes. Despite being less prevalent than other substances, sesquiterpenes have a disproportionately large impact on cloud formation. In fact, they form ten times more particles than other organic substances at equivalent concentrations.

This study’s findings underscore the need to reconsider the role of sesquiterpenes in climate models, potentially rendering many existing models obsolete.


Conclusion:

For those who’ve been echoing the mantra that climate science is “settled” and beyond dispute, this study serves as a stark reminder of the complexities and unknowns still at play. It’s high time to question the wisdom of pouring vast sums of money into policies based on potentially flawed models. The discovery of sesquiterpenes’ role in cloud formation is a testament to the ever-evolving nature of climate science—a field that is far from settled.

Yup.

“In a recent revelation from the international CLOUD project at the nuclear research center CERN, researchers have identified sesquiterpenes—gaseous hydrocarbons released by plants—as a pivotal factor in cloud formation.”

I have more than once speculated here that coniferous trees emit such large amounts of isoprene and terpenes into the atmosphere for other reasons than making pine forests smell nice.
Excellent absorbers of not just IR, but also UV in the same range of ozone. A great idea for producing photo-ionization leading to nucleation centers for water condensation and thus cloud formation.

As you say, Duh.

Yup. The Great Smokey Mountains are ‘Smokey’ (foggy) in summer because of isoprenes and terpenes released by the trees. A piney forest smelled piney because of isoprenes. That has been known for decades. CERN discovering that climate models do not account for this is interesting, but minor compared to other BIG climate model deficiencies.

In the late 1890s leading physicists such as Lord Rayleigh declared that there was no further progress to made in physics the science was settled. Then in 1900 came Plank’s black body radiation law to solve the ultraviolet catastrophe highlighted in the Rayleigh Jeans law of classical physics. Planck’s quanta of energy revolutionized physics the science was anything but settled.

Reply to  Gary Pearse
October 1, 2023 2:25 pm

Gavin’s problem is that HE does not know why, while many skeptics do. There are three biggies:

  1. CFL computational intractability at meaningful physical scales forces parameterization. CMIP requires parameter tuning to best hindcast. And that drags in the natural variation attribution problem. And natural variation exists per AR4 SPM1 fig 4.
  2. IPCC says models show cloud feedback is something significantly positive. Observations show it is zero or slightly negative.
  3. Models get water vapor feedback too high by a factor of about 2. This is shown by the modeled but nonexistent tropical troposphere hotspot. The only CMIP6 model that doesn’t have one is INM CM5—parameterized using actual ARGO ocean rainfall, about twice what was guesstimated—so lower WVF by about half.

Separate comment about 2&3, previously provided several times in comments. INM CM5 has an ECS of 1.8. Plug the cloud and WVF corrections into Lindzen’s Bode feedback curve (zero feedbacks = ECS 1.2C) yields an IPCC adjusted ECS of 1.8. Nice triangulation.

“PCC says models show cloud feedback is something significantly positive. Observations show it is zero or slightly negative.”

Positive feedback from water vapor is an essential part of the human-caused climate change theory. According to this theory, CO2 alone cannot raise the temperatures much without the help of a positive water vapor feedback.

But, as noted above, observations do not show a positive water vapor feedback, even after all these years. Therefore, the human-caused, CO2-derived, climate change theory is wrong.

Sesquiterpenes are one of the CARB’s evil VOCs, volatile organic compounds, that they “regulate” to “prevent ozone”. The levels of VOCs in the Los Angeles Air Basin exceed standards purely from natural sources. (If you can smell sagebrush or eucalyptus, it is emitting VOCs).

So was there a shortage of turpenes, therefore nucleation sites, therefore cloud cover, before the boreal forests existed, when the north was covered with a mile of ice ? Resulting in more sunshine ? Well NO. Turpenes are just one of many potential nucleators, the most numerous being ice crystals themselves falling from higher altitudes where water droplets might have hit temperatures below freezing before they formed and fell. Falling Ice crystals finally warming up to the freezing point due to atmospheric Lapse rate is why those fluffy clouds are flat on the bottom…

Fred H Haynie
October 1, 2023 7:22 am

There is much more cloud formation over our vast oceans where there are no trees. Clouds form when atmospheric water vapor condenses. That water vapor comes from the evaporation of surface water. The temperature at the interface is near the dew point of the atmosphere just above it. Water vapor is lighter than air and rises. The air with water vapor cools as it rises. When it reaches the dew point, the water condenses forming clouds.

You don’t need many nucleation points. At around -48 C H2O becomes an ice particle whether or not nucleation points exist. Thats below the tropopause. Then it can fall to lower altitudes and become a nucleation point itself for more water vapor condensation.

Actually, Lovelock’s ‘Gaia Hypothesis’ proposes that Earth’s temperature is homeostatically self-regulating, i.e. thermostatically controlled, in which case any excessive (by Gaia’s intrinsic criteria) anthropogenic global warming is doomed to nullification in time as Gaia’s thermo-regulatory processes (i.e. negative feedbacks of one sort and another) get activated and swing into effect.
 
However, no modern-day [post-modern] ‘Gaia-worshippers’ appear to know anything about that as far as I can tell.

Coding sesquiterpenes into climate models is a daft idea. It would be like coding in the movement of butterflies in the Amazon – the ones that feature in chaos theory. As currently structured, the models can never work no matter what you code into them because they work with the micro. They need to drop the micro and work with the macro.

Clio, they can’t. The CFL constraint means that modeling on physically meaningful scales (convection cells are 2-4km across) is computationally intractable by about 6-7 orders of magnitude. Hence they are parameterized. The parameters are tuned to best hindcast. That drags in the natural variation attribution problem. Models assume it away, so forecast too hot by about 2x. A feature, not a bug.

Sorry for the off-topic segue, but the article is another example of journalists and scientists straining to find some climate warming angle in any issue – and by doing so I think they hard “Science” since these intellectually lazy people aren’t looking for real details and causes.

With the puffins – they are generally doing great, but a bunch of ‘pufflings’ show up small and malnourished near a town and suddenly the scientists have blamed warmer oceans because the parents would have to swim deeper to get fish that would need to swim lower to stay out of the heat.

Big face-palm – so many things wrong with that propaganda – it’s definitely not a proper theory – considering that if the water is even warming off the coast of Newfoundland, some fraction of a degree isn’t going to make the fish swim any lower.

So while these climate fanatics hog the limelight, the focus if off finding the real culprit if there even is one, given that the puffin colony in general is doing very well.

This is just more of the same nonsense. The formation of clouds over oceans regulate energy uptake and loss. Their formation is inevitable and a function of the surface temperature. The notion that chemical nucleation is required is silly. And trees only cover a small portion of Earth’s surface.

You do not need to observe clouds over water for very long to understand their formation is a function of the surface temperature. From surface fog at low temperature to fluffy puffs around 15C and on to angry cumulonimbus at the maximum sustainable of 30C

The only people I see claiming that scientist are saying “climate science is settled” are self-proclaimed ‘skeptics’; those trying to say “if something about any given subject is not fully understood, then nothing about it can be understood”.

It does not follow that just because not everything is known about any given subject then nothing can be known about it, ever. That’s just silly. Like saying that because you have not completed a 3,000 piece jig-saw puzzle means that all the parts you have completed to date must be wrong. And some will be, but the picture improves with every piece.

You never see climate scientists claiming that their work is “settled”. You only see fake skeptics saying that climate scientists say “the science is settled”. If climate scientists thought the science was “settled” they’d be out of work, right? So the last people who’d want the science to be ‘settled’ are those engaged in it.

Land use change is one of the only ways that man can significantly influence the climate. This is usually on a local or regional level, but wide spread land use change can affect entire continents.

I would hope that they don’t latch onto this though, or the authoritarians will use fear based propaganda to get populations to demand that everyone is locked in a few densely populated and tightly controlled cities.
